I believe most of my questions relate GR: 1.) I've heard of gravity likened to a bowling ball sitting on a spring mattress. The mattress is deformed or warped around the bowling ball, creating an indentation. The explanation discusses that this is analogous to a massive object, e.g. a star, warping the fabric of spacetime around itself. Is this understanding of gravity correct? Is gravity a force field at all or an aspect of the local topography of spacetime? Does the warping effect of a gravitational field warp the time dimension of spacetime and if so what effect does it have on time and how does it achieve this? Does a gravitational field cause length contraction and time dilation? I've heard that all massive objects exert a gravitational force on all other objects. If this is true does this mean that all of spacetime is warped by an omnipresent gravitational field and is this why spacetime is described as being curved? Do physicists visualize the force of attraction of a gravitational field as a vector space or in some other way? Are gravitational waves caused by an accelerating gravitational field, e.g. a bowling ball that is at rest on a water mattress being pushed, causing a ripple/wave in the water? 2.) Does gravity pull/attract objects through the time dimension as well as the space dimension, and if so what is the significance of this? Does the manipulation of time by gravity have any correlation with the inability to escape a black hole after passing through the event horizon?(I heard this has to do with something called light cones but I haven't the slightest clue of what they are or how they relate to gravity.) 3.) Is there any correlation between a gravitational field and a electromagnetic field? Do electric and magnetic fields create the same kind of warping in spacetime as gravity does? If so, is the geometry of spacetime warped in different ways for opposite charges and is this why opposite charges attract? In reference to the force of gravity acting like the bowling ball on a mattress, would like charges be similar to two depression meeting or two anti-depression meeting and repelling one-another? Do gravitational waves behave like or share any properties with electromagnetic waves? Do gravitational waves lose energy as they propagate through spacetime and are they absorbed and re-emmited like electromagnetic waves? Is gravity in any way similar to the property of electric charge and if so would the opposite charge of gravity be that of dark matter? If dark energy is expanding spacetime, which I assume to be true, does gravity contract spacetime between two massive objects or does it just create an attractive force between the particles and decrease the distance between them? Do electromagnetic fields expand or contract their local spacetime? Is light slowed down or does it lose energy when it interacts with a gravitational field, e.g. a car slowed down by speed bumps or pot holes in a road? Does the speed of light have anything to do with gravitational fields? 4.) I know that light, which is an electromagnetic wave, can be bent around a massive object's gravitational field. Is it possible for a gravitational wave to be bent by a strong electromagnetic field? I have heard that magnetars have a strong magnetic field, and that strong gravitational waves can be produced by the merger of two black holes. Are the statements in the previous sentence valid, and if so would it be possible to view the gravitational waves bending around a magnetar like Eddington viewed light bending around the solar eclipse of 1919? I have no background in physics, so if any of these statements or questions are misconstrued , blatantly incorrect or unknown at this time feel free to correct them. Also, I apologize if some of my questions are redundant. Thank you.
